Treatment of two cases of perigraft seroma with fistulization to the skin.

Perigraft seromas are an uncommon complication of prosthetic vascular reconstructive surgery. The unclear etiology is perhaps partly responsible for a delay in diagnosis. Two cases with fistulization to the skin after implantation of a Dacron graft are presented. Relation to the graft material was observed in the first patient where successive identical graft implants caused each time recurrence of symptoms. In both patients the condition was successfully treated only after removal of the affected graft and replacement with a polytetrafluoroethylene prosthesis.
